command, this can be a useful way to define shell functions for other commands
to use.
+=item fixups
+
+If the "fixups" parameter is set, its command is run whenever a repository
+is checked out, or updated. This provides an easy way to do things
+like permissions fixups, or other tweaks to the repository content,
+whenever the repository is changed.
+
+=item pre_ and post_
+
+If a "pre_action" parameter is set, its command is run before mr performs the
+specified action. Similarly, "post_action" parameters are run after mr
+successfully performs the specified action. For example, "pre_commit" is
+run before committing; "post_update" is run after updating.
+
=back
When looking for a command to run for a given action, mr first looks for
override these rcs specific actions. To add a new revision control system,
you can just add rcs specific actions for it.
-The ~/.mrlog file contains commands that mr has remembered to run later,
-due to being offline. You can delete or edit this file to remove commands,
-or even to add other commands for 'mr online' to run. If the file is
-present, mr assumes it is in offline mode.

=head1 UNTRUSTED MRCONFIG FILES
Since mrconfig files can contain arbitrary shell commands, they can do
anything. This flexibility is good, but it also allows a malicious mrconfig
file to delete your whole home directory. Such a file might be contained
-inside a repository that your main ~/.mrconfig checks out and chains to. To
-avoid worries about evil commands in a mrconfig file, mr
-has the ability to read mrconfig files in untrusted mode. Such files are
-limited to running only known safe commands (like "git clone") in a
-carefully checked manner.
+inside a repository that your main ~/.mrconfig checks out. To
+avoid worries about evil commands in a mrconfig file, mr defaults to
+reading all mrconfig files other than the main ~/.mrconfig in untrusted
+mode. In untrusted mode, mrconfig files are limited to running only known
+safe commands (like "git clone") in a carefully checked manner.
+
+To configure mr to trust other mrconfig files, list them in ~/.mrtrust.
+One mrconfig file should be listed per line. Either the full pathname
+should be listed, or the pathname can start with "~/" to specify a file
+relative to your home directory.
-By default, mr trusts all mrconfig files. (This default will change in a
-future release!) But if you have a ~/.mrtrust file, mr will only trust
-mrconfig files that are listed within it. (One file per line.) All other
-files will be treated as untrusted.
+=head1 OFFLINE LOG FILE
+
+The ~/.mrlog file contains commands that mr has remembered to run later,
+due to being offline. You can delete or edit this file to remove commands,
+or even to add other commands for 'mr online' to run. If the file is
+present, mr assumes it is in offline mode.
=head1 EXTENSIONS
files providing such extensions are available in /usr/share/mr/. See
the documentation in the files for details about using them.
+=head1 EXIT STATUS
+
+mr returns nonzero if a command failed in any of the repositories.
